中文摘要：
VVIC是一种新的害鼠控制技术．应用生物学家想从理论上研究其有效性，从而可以用于评估和指导实验．我们建立一类年龄结构的VVIC技术控制下害鼠种群动力学模型，考虑其动力学性质，得出病毒感染性的强弱对控制一雄一雌或一雄多雌婚配制度害鼠种群影响非常大．同时也得到不育年龄可以导致模型产生周期振荡现象．
英文摘要：
Virus-vectored immunocontraception （VVIC） is a new method used to manage vertebrate pests. In order to predict its efficiency,we formulated a mathematical model with age structure to investigate the dynamics of population controlled with VVIC. The dynamical behaviors of these models are investigated. We concluded that employing virus with powerful infectivity as vectors to control monogamy or polygyny vertebrates guarantees better control effect. Meanwhile, we find that the immunocontraception age can lead to periodic phenomenon.
